Novel nanostructures for efficient long-range energy transport

The conversion of sunlight into electricity at low cost becomes increasingly important to meet the world's fast growing energy consumption. This task requires the development of new device concepts, in which particularly the transport of light-generated energy with minimal losses is a key aspect. An interdisciplinary group of researchers from the Universities of Bayreuth and Erlangen-Nuremberg (Germany) report in Nature on nanofibers, which enable for the first time a directed energy transport over several micrometers at room temperature. This transport distance can only be explained with quantum coherence effects along the individual nanofibers.

This is a supramolecular nanofiber consisting of more than 10,000 perfectly ordered building blocks, which enables an energy transport over a distance of more than 4 micrometers at room temperature.

Surprising discoveries about 2-D molybdenum disulfide: Berkeley Lab researchers use award-winning campanile probe on promising semiconductor

Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have used a unique nano-optical probe to study the effects of illumination on two-dimensional semiconductors at the molecular level. Working at the Molecular Foundry, a DOE Office of Science User Facility, the scientific team used the "Campanile" probe they developed to make some surprising discoveries about molybdenum disulfide, a member of a family of semiconductors, called "transition metal dichalcogenides (TMDCs), whose optoelectronic properties hold great promise for future nanoelectronic and photonic devices.

With the Campanile probe, optical excitation and collection are spatially confined to the nano-sized gap at the apex of the tip, which is scanned over the sample, recording a full emission spectrum at each position.
